Choose your counting system, shoe size and unit to see what to bet at every count, with the estimated edge at each step. Then enter your running count and decks left to get your next bet.
| Count | Bet | Amount | Edge |
|---|---|---|---|
| Below +1 | 1 unit | $25 | −0.48% |
| +1 or higher | 2 units | $50 | +0.02% |
| +2 or higher | 4 units | $100 | +0.52% |
| +3 or higher | 8 units | $200 | +1.02% |
| +4 or higher | 12 units | $300 | +1.52% |
Spread: 1–12 units ($25–$300), 12 to 1.
The estimated edge is the house edge for your rules plus about 0.5% for each Hi-Lo true count point (0.46% to 0.51% depending on the system). It is shown at the lowest count in each step, and at a count of 0 for the 1-unit step. It is an estimate for practice, not a guarantee. The app rounds it to one decimal place, so it shows −0.5% where this table shows −0.48%.
Counting Edge sizes every bet in units from one five-step ramp: 1, 2, 4, 8 and 12 units, a 12 to 1 spread. You decide what a unit is worth.
Balanced counts bet from the true count to one decimal place, so a Hi-Lo true count of +3.9 is still an 8-unit bet and +4.0 is 12. New to the true count? Use the true count calculator, or read how spreads fit into the beginner's guide.
The count at which each balanced system raises its bet. These are true counts.
| System | Scale vs Hi-Lo | 2 units | 4 units | 8 units | 12 units |
|---|---|---|---|---|---|
| Hi-Lo | 1 | +1 | +2 | +3 | +4 |
| Hi-Opt II | 1.67 | +1.7 | +3.3 | +5 | +6.7 |
| Omega II | 1.79 | +1.8 | +3.6 | +5.4 | +7.2 |
| Zen Count | 1.79 | +1.8 | +3.6 | +5.4 | +7.2 |
| Wong Halves | 1.05 | +1 | +2.1 | +3.1 | +4.2 |
For KO and ReKO the 2-unit bet starts at the key count, which depends on the shoe. The 4, 8 and 12-unit bets start at running counts of +4, +8 and +12 in every shoe.
| Shoe | KO start | KO key count | ReKO start | ReKO key count |
|---|---|---|---|---|
| 1 deck | 0 | +2 | −2 | +2 |
| 2 decks | −4 | +1 | −5 | +1 |
| 4 decks | −12 | −2 | −11 | −1 |
| 6 decks | −20 | −4 | −17 | −3 |
| 8 decks | −28 | −6 | −23 | −5 |
KO publishes key counts for 1, 2, 6 and 8 decks. For other shoes, such as 4 decks, Counting Edge uses 2 minus the number of decks. Details: KO.
Every table has a maximum bet. If 12 units is more than the maximum, the top steps all become the maximum and your spread shrinks. Enter your table maximum above to see it. With a $25 unit and a $250 maximum, 12 units ($300) is capped at $250, so the spread is 10 to 1 instead of 12 to 1.
This calculator is for practicing at home. Counting Edge teaches when to size up, not how much to bet: you choose the unit. It is not for use at a casino table.
Counting Edge tracks the count as you tap cards and shows the bet from this ramp, for all seven counting systems. Free and open source.
